python-BitVector-3.4.9-bp151.1.1

- Update to 3.4.9:
  * Version 3.4.9, in addition to implementing __iadd__, also includes a
    significantly faster implementation for __add__.  For extending a given
    instance of BitVector, the implementation for __iadd__ adds bits to the
    existing instance as opposed to creating a new instance.  These changes
    to the module should make it easier to solve larger problems more
    quickly with BitVector.

- Initial version, needed by python-raet
